I am not trying to draw attention to caches by doing this topic, just curious!
I have run a search for caches with "series" in their name and of course got over 40 pages of results all over the globe.
How many series caches are there in this country?
Maybe a competion could be run for the first team to complete them all????
By series i mean a load of caches which by visiting one you gain half or even a quarter of a co-ord so that you can gain a higher level!
I have found so far via searches:
Alchemy series
Zodiac Series
Road to the Wrekin series
Quest of the ring (a multi but has to be included)
Spectrum series
Chess pieces
anybody want to add some more?
